$\left(a+9\right)^2-2\left(a+9\right)=0$
Learn how to solve classify algebraic expressions problems step by step online. Find the break even points of the expression (a+9)^2-2(a+9). Find the break even points of the polynomial \left(a+9\right)^2-2\left(a+9\right) by putting it in the form of an equation and then set it equal to zero. Expand the expression \left(a+9\right)^2 using the square of a binomial: (a+b)^2=a^2+2ab+b^2. Multiply the single term -2 by each term of the polynomial \left(a+9\right). Combining like terms 18a and -2a.
